We regret enabling multi-currency as it has only created more problems for our business and unfortunately once enabled there's no way to revert back. I see many posts from community members on the wide range of issues caused by multi-currency. QB should investigate these issues and put fixes in place. Create the ability to turn off multicurrency. Listen to your customer's input instead of simply directing them to submit a suggestion - it's clear from reading many of the other posts that customer suggestions are rarely implemented.
